Customizable Sprite Killer

any reason a red vertical koopa goes right through this block? it worked for some sprites

a must have! works perfectly! thanks Nowieso!

For some reason the stun timer is not set, so there is no puff of smoke (or there's a very long one if you kill a stunned sprite, like a Goomba). Add this after "STA !14C8,x" to add the puff of smoke:

LDA #$1F
STA $1540,x

yes yes yes . thanks nowieso for bringing to us the holy grail. been searching for something like that for month

Tested with:
-Lunar Magic 3.11
-SA-1 1.31
-GPS 1.4.1
-ZMZ 1.08

This block is optimal if you don't care about specifics but if you wish to add exceptions for which sprites can be killed, you should check Sprite Kill Muncher.
